PERMUTAION-PADLOCK.

Specification of Letters Patent.

Patented Nov. 21, 191e?.

Application filed June 1, 1916. Serial YNo. 101,052.

To all vwhom t may concern.'

Be it known that I ,S'raNisLaw A. Pinos, a subject of the Czar of Russia, residing at Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Permutation-iadlocks, of which the following iis a specification.

This invention relates to certain new and useful improvements in permutation padlocks.

The primary object of the invention is to provide a keyless padlock adapted for operation when permutation members are manipulated in a predetermined manner, the

lock being capable of releasing by only an authorized person.

A further object of the device is to provide a padlock constructed with permutation members rendering it unnecessary'to employ a key for manipulating the lock and adapted to release theshackle only when the permutation members are set in a certain manner, thus insuring` the device against thieves picking the same.

lVith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, -combination and arrangementof parts hereinafter more fully described, illustrated in the accompanying drawings, and then claimed.k l

ln the drawings forming a part of this application and `in which like designating characters refer to correspondingv parts throughout the several views, Figure 1 is a side elevation of a padlock of the present form. Fig. 2. is a top plan view thereof. Fig. 3 is a view similar toFig. 1 with the face plate of the casing removed and with the mechanism shown in section. Figs. 4 and 5 are transverse sectional Views taken respectively, upon lines lV-IV and V-V of Fig. B. Fig. G is an enlarged detail sectional view illustrating two of the permutation members, one in its releasing and the other in its locked position. Fig. 7 is a view similar to Fig. G showing two permutation members in their releasing position and the locking bolt in its retracted released position, and, Fig. 8 is a transverse sectional view upon line VIll-VHI of Fig. 7.

The present lock consists of a substantially rectangular casing 10 having a cover plate 11 while a. swinging shackle 12 is pivoted at one end upon a pin 13 'in a manner to allow its opposite end 1a to move inwardly and outwardly of an open slot 15 in the casing, it being understood that the said shackle end 1eis provided with a locking hook 1G.

Mounting brackets 17 and 1S are arranged within the casing 10 beine' secured to the opposite sides thereof by means of projecting lugs 19 carriedby the said brackets and projecting through the casing sides, the said brackets being adapted Vfor slidably mounting a bolt 20. @ne end of the bolt 2O normally projects outwardly of the casing 10 through an opening Q1 in the end wall thereofl while the opposite end of the said bolt is arranged within the casing and carries a hook-shaped locking head 22 adapted for engaging in the hook 16 of the shackle 12 when the shackle end 1d is normally positioned inwardly7 of the casing slot 15. as an integral part of the bolt F20. A. coil spring 23 connects the locking head with a depending perforated lug Qll carried by the pivoted end of the shackle 16, which spring 23 maintains the bolt 2O normally project-ed in its locking position as bes-t illustrated in Fig. 3 of the drawing. T he holt Q0 is ar "anged upon one side thereof with a plurality of identical wards 25, the ward which is positioned nearest the locking head 2Q being slidable inwardly of a notch 26 in the bracket 18 when the bolt is retracted.

A plurality of chambered permutation disks or members-27 are journaledupon the bolt by means of cent-ral perforations Q8 centrally arranged through the said disks and through which the bolt extends, the disk being arranged between the two brackets 17 and 18. The chambers 29 of the disk 2T are arranged for the free rotation of the disks with the wards arranged within the said chambers while slight-ly flaring radial Vnotches 30 extend from the perforations 28 of the disk Q7 for allowing the wards Q5 to freely slide therethrough when the disks r'are properly positioned with trie notches 30 in alinement with the said wards. rlhe peripheries of the disks 9.7 project through the slots 31 in the side plates of the casing 10 which allows the disks 27 to be freely rotated by means of the operator. Permutation designations such as the numerals 32 are provided upon the peripheries of the disks 27, the correct combination being known by the owner of the lock for positioning the notches 30 of each of the disks The locking-head 22 is preferably made.

27 in alinement with the notch 2G of the bracket 1S as well as in alinement with the wards 25. When all of the disks 27 are positioned in this manner the outwardly projecting end of the bolt 20 may be engaged for pushing the bolt longitudinally inwardly of the casing 10, allowing the wards 25 to pass through the disk notches 30 and releasing the locking head 22 from the shackle hook 16, at the time of which release, the spring 23 automatically swings the shackle 12 to its open position. Upon releasing the pressure from the bolt 20, the same is again projected by the spring 23 and the shackle will become locked upon being closed the curved end face 33 of the shackle end 14 freely riding over the curved face 34 of the locking head 22. The disks 27 are then turned for bringing the notches 30 out of alinement with the wards 25 so that the bolt 2O will remain locked until again released in a similar manner.

A padlock is thus arranged possessing great strength and while readily manipulated by the authorized owner conversant with the correct combination for manipulating the permutation members, the same is substantially non-pickable and thief-proof.

.The present form of the device is believed to be preferable although it will be understood that minor changes may be made if desired without departing from the' scope of the invention as claimed.

lVhat I claim as new is l. A permutation lock comprising a casing having opposite slots therein, mounting brackets within said casing secured to the opposite side plates thereof, one of the said brackets having a notch therein, a bolt slidl ably mounted through the said brackets and having a plurality of outwardly Haring wards arranged in alinement with the said notch, a swinging shackle pivoted at one end within the said casing and having a hooked free end positioned within the said casing when in its locked position, a locking head carried by the inner end of said bolt normally arranged within the path of movement of the said hooked end of the shackle, resilient positioning means for the said locking head, automatic swinging means for the said shackle fixed at one end to the inner pivoted end of the shackle and at its other end to said locking head, and a plurality of permutation members journaled upon the said bolt and projecting through said side slots of the casing arranged with notches positioned in alinement with the said bracket notch and bolt wards when the said device is in its unlocked position.

2. A lock comprising a casing, a swinging shackle having one end pivoted within the said casing and provided with a perforated lug, the other end of the said shackle forming a locking hook projecting inwardly of the casing when in its locked position, a slidable bolt mounted within the casing having one end normally projected therefrom, a locking head carried by the inner end of the said bolt and immovable relative thereto arranged within the path of movement of the said shackle hook, a positioning spring connected at one of its ends to said perforated lug and at its other end to said locking head, and permutation engaging means carried by the said bolt.

3. A lock comprising a casing, a swinging shackle having one end pivoted within the said casing and provided with a perforated lug, the other end of the said shackle forming a locking hook projecting inwardly of the casing when in its locked position, a slidable bolt mounted within the casing having one end normally projected therefrom, a locking head carried by the inner end of the said bolt and immovable relative thereto arranged within the path of movement of the said shackle hook, a positioning spring connected at one of its ends to said perforated lug and at its other end to said locking head, radial projecting flaring wards carried by the said bolt in alinement with.

each other, a plurality of permutation disks journaled upon the said bolt and having chambers for the normal reception of the wards and being further provided with radial notches arranged in alinement with the wards when the disks are in their released positions, the opposite side plates of the casing being provided with longitudinal slots through which the peripheries of said disks freely project, and permutation characters arranged upon the peripheries of the disks.

In testimony whereof I aiiix my signature.
